Patented May 31, 1932 UNITED STATES PATENT OFFICE LOUIS E. PITTONI, OFJAMAICA, NEW YORK, ASSIGNOR TO THE ROME COMPANY, INC., A CORPORATION OFNEW YORK CONNECTION BETWEEN SPRINGS AND FRAMES Application filedFebruary 10, 1930. Serial No. 427,108.

The present invention relates to bed springs or other cushions composedof connected vertical coiled springs surrounded by an enclosing frame ofheavy wire lying approximately in the plane of the tops of the springs.

The object of the invention is to produce a simple and novel connectionbetween the frame and the adjacent coiled springs.

The various features of novelty whereby 110 my invention ischaracterized will hereinafter be pointed out with particularity in theclaims; but, for a full understanding of my invention and of its objectsand advantages, reference may be had to the following deiifi taileddescription taken in connection with the accompanying drawings, wherein:

Figure 1 is a plan view of a bed spring embodying the present invention,only a portion of the coiled springs being shown; Fig.

2 is a plan view, on a much larger scale than Fig. 1, showing fragmentsof the frame and one of the coiled springs and the connection betweenthe same; Fig. 3 is a section on line 3-3 of Fig. 2, on a still largerscale; and Fig. 4 is a view similar to Fig. 3, showing a modification. 7

Referring to Figs. 1 to 3 of the drawings, 1 represents a frame,composed of a heavy wire or light rod surrounding a cushion composed ofmany vertical coiled springs 2, 2;

the frame and the spring cushion being of any usual or suitableconstruction.

In accordance with my invention, I secure the frame to the upper turnsor coils of the adjacent springs, that is, the springs forming theborder of the cushion, by means of simple clips extending around thewires of the springs and welded to the frame. These clips are preferablymade of strips of sheet metal. In the arrangement shown, each clip ismade of a long rectangular piece of sheet metal bent upon a transverseline about midway between its ends to produce two wings 3 and 4 lyingflat upon each other and connected by a tubular section 5 fitting aroundthe wire in the upper turn of one of the springs. The parts 3 and 4 arepreferably of such length that when the clip is brought up against theunder side of the frame, the free end of the clip lies inwardly from thevertical plane containing the long axis of the frame wire; the springand the frame wire being so positioned that the elements 3 and 4 extenddownwardly and laterally to come into contact with the frame. The freeend of the clip and the frame are then welded together with the weldingcontacts on a line extending inwardly and downwardly. The spring is thusfirmly connected to the frame, and the free end of the clip lies aconsiderable distance inwardly from the vertical plane tangent with theoutside of the frame. Consequently, if there should be any roughness atthe end of the clip, the danger of tearing the bed clothing by contacttherewith is eliminated, because the frame will hold the bed clothingfar out from the adjacent end of the clip.

If desired, the strip from which the clip is formed may be longer thanthat required to produce the clip shown in Fig. 3, so that the engagedwing sections thereof, as indicated at 6 and 7 in Fig. 4, may be curvedtoward the end of the clip so as to fit against the under side of theframe and extend outwardly beyond the vertical plane containing the longaXis of the frame.

It will thus be seen that I have produced a simple and novel means forconnecting the surrounding frame to the adjacent wires of a springcushion, without requiring special attention to be paid in finishing theedges at the free ends of the strips or bands of which the strips aremade, because the points at which there may be a little roughness are sopositioned angularly of the wire or rod of which the frame isconstructed that the bed clothing will not catch on the same.Consequently the frame and the springs may be assembled quickly and atlow cost, with the assurance that the fastenings between the springs andthe frame will not be displaced along the latter in use. Furthermore,the material of which the clips are made may be thin so that the partsof the frame that are normally visible when the bed spring is on a bedpresent either an entirely smooth surface or, in the case of the clipshown in Fig. 5, a surface that is for all practical purposes smooth andcontinuous.

lVhile I have illustrated and described with particularity only a singlepreferred form of my invention, with a few modifications, I do notdesire to be limited to the 5 exact structural details thus illustratedand described; but intend to cover all forms and arrangements which comewithin the definitions of my invention constituting the appended claims.

I claim 1. In a bed spring, a group of vertical coiled springs, a frameof wire surrounding said group and positioned in about the plane of theupper turns of the spring, individual clips in the form of pieces ofsheet metal each bent around and completely enclosing the wire of theupper turn of a spring and having the end portions resting flat againsteach other, and said end portions extending from the said wires of theupper turns of the springs underneath the frame wire and being weldedthereto.

2. In a bed spring, a group of vertical coiled springs, a frame of wiresurrounding i225 said group and positioned in about the plane of theupper turns of the spring, individual clips in the form of pieces ofsheet metal each bent around the wire of the upper turn of a spring andhaving the end portions resting flat against each other, and said endportions extending underneath the frame wire and being welded thereto,the extreme end of each clip lying inwardly from a vertical planecontaining the long axis of the corresponding part of the frame wire.

In testimony whereof, I sign this specification.

LOUIS E. PIT'IONI.
